Anybody running 20 inch wheels and rub when turning at certain angles on a slope?

I'm running 255/30R20 ADV7.1 wheels on OEM suspension on the front of my car and it rubs only when the steering is 3/5 turned in either direction and on a slight slope(I mean slight, only a couple degrees).

I am looking at coilovers to solve the problem, but I want to be 110% sure it will be resolved. I don't want to just keep running in circles trying over and over again.

the stock 245/35/19 tire has a diameter of 25.75in while the tire that you are running has a diameter of 26.02in, so the current tire is a little larger than the stock tire size. the solution is for you to use a slightly smaller tire. your rubbing issue will go away if you used 245/30/20
